If you have changed both sensors you will need to track down the wires. I will email the wires to test and the procedures. This will only tell if wires are bad, not the sensors:

I had a similar problem to an earlier post with respect to intermittent stall on my 1996 grand voyager. Before I had a chance to get my OBDII reader, the van would stall maybe five times per trip, and idle slightly rough at a stoplight. I thought it might be some water in the gas, and added some gas treatment. It helped a bit, brought it down to two stalls per trip. I finally got the OBDII reader online, and it came up with a P1391. I just replaced the cam and crank sensors, and now it will not start. Turns over, nothing on the reader. Any thoughts? Is it that difficult to put in a sensor?
